LAMP.

Application filed June 28, 1915.

To all whom it may concern:

Be it known that I, LEO L. PFEIFER a citizen of the United States, residing at 610- lumbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Lamps, of which the following is a specification. 7

My invention relates to lamps of the 011 burning type, the invention itself being particularly adaptable to such lamps as are used in connection with motor vehicles.

The main object of my invention resides in the provision of a structure so constructed as to prevent the snufling out of the flame when the vehicle is in movement, the lnvention being particularly efiective under fast movement of the vehicle. To this end, I have provided a peculiar type of guard arrangement for encircling the lower portlon of the burner structure to so direct whatever air may enter, that it will not interfere with the proper burning of the flame.

The preferred embodiment of my invention is shown in the accompanying sheet of drawings, in which similar characters of reference designate corresponding parts, and in which:

Figure 1 is a central vertical section taken through my improved lamp, Fig. 2 is a View in side elevation showing the oil receptacle which forms a portion of my lamp, detached, and, Fig. 3 is a top plan view of the structure shown in Fig. 2.

In the drawings, there is shown a superstructure comprising a main casing body 1 provided with a lens 2 at its forward side, an inner member or reflector 1 spaced from the body 1 to form a space 1", and a chimney structure 3 at its top. The present 1nvention has no particular bearing on this portion of the structure and, therefore, a detailed description of this portion will not be entered into. Cooperating with this superstructure there is an oil receptacle 4: provided with an inwardly extending shelf structure 5 centrally apertured to receive the oil burner designated generally by the reference numeral 6. This oil burner is of the conventional type and is held clamped between the superstructure and the oil receptacle as is shown by the peculiar mounting of the inner member 1 This oil burner is also constructed to present an L- shaped base flange 7 shown in Figs. 1 and 3, the vertically arranged leg being designated Specification of Letters Patent.

T and the horizontally disposed leg of this flange being provided with a plurality of apertures designated 8, these apertures serving in a manner to permit a flow of air suflicient to support combustion from the apertures 15 and 16 and through the space 1 all of. the superstructure. The lower part of that portion of the superstructure formed by the casing body 1 is provided with a depending annular flange such as is shown at 9, this flange being provided with a plurality of inwardly and radially extending pins 10. These pins 10 are designed to operate in bayonet slots 11 carried by a similarly arranged flange 12, this latter flange being carried by the upper portion of the oil receptacle 4 above the shelf 5. Both the flanges 9 and 12 are provided with slots to accommodate the thumb screw wick regulator shown at 13. A lamp constructed as thus far described is somewhat hard to keep in a lighted state, especially when mounted on a motor vehicle and this vehicle traveling at a comparatively high rate of speed, since the flange 12 is cut up to some extent to accommodate the bayonet slots 11 and further, since it is practically impossible to provide an air tight joint between the. flanges 9 and 12. More or less air seeps in and inasmuch as the slots 11 terminate at a point below the level of the horizontal leg forming the L-shaped flange 7, this in-rush of air passes up through the apertures 8 and snuifs out the flame. To guard against this seepage of air, I have provided the shelf 5 with a second flange designated 14, this flange 14 being annular in form and concentric with the flanges 9 and 12, although somewhat less in diameter than either one of them. Reference to Fig. 1 will disclose that the top of this flange 14.- extends to a point above the level of the lower edge of the vertical leg of the L-shaped flange 7 and thus any air that may seep in and enter the space between the flanges 12 and 14 by way of the slots 11 is deflected upwardly and thus out of the direct path of the air passing through the apertures 8. In this way the flame is not interfered with and the lamp may be made to move through the air at a very high rate of speed and still be maintained in a lighted condition. "t

From the foregoing description, taken in connection with the accompanying sheet of drawings, it will be apparent that I have are provided an invention which in itself is comparatively simple, but which in reality is very effective when in use and as a matter of fact renders the use of this type of lamp practical. An important feature of the arrangement is that the flange 14 extends upwardly to a point above the level of the lower edge of the vertically disposed leg forming a portion of the L-shaped flange 7. What I claim, is: In an oil burning lamp, a superstructure, an annular flange on the lower portion of said superstructure, rigidly arranged pins carried by said flange, an oil receptacle, an annular flange carried by the upper portion of said receptacle formed with bayonet slots arranged to cooperate with the pins on said first named flange, a burner structure operatively carried by said receptacle, an L- shaped base flange carried by said burner, one leg of said base flange being horizontally disposed and having a plurality of air holes therein, the other leg of said base flange depending from the outer edge of said horizontal leg, and a guard flange carried by said receptacle, said guard flange being smaller but concentric with said first and second named flanges and extending to a height above the lower edge of the depending leg of said L-shaped flange.

In testimony whereof I aflix my signature in presence of two witnesses.
